So far it seemed that PB is not involved in the SciFi game. Different studio, different city, licensed technology (Unreal). The only connections officially admited are (a) the PB name (-> which hints at legal & financial connections ), (b) Mike Hoge, (c) the PB managing director doing the legal paperwork for the new studio and (d) the possibility to offload some contract work from PB Red to PB.
Atleast risen 3 was financially successfull enough. I thought it was a fun game to play through, but I keep hoping them to release something more memorable next time.
